• Threaded stud located near the outlet for attachment of tank sensors
• Temperature and pressure relief valve included
• Collector feed and return fittings located at front of tank for convenient installation
• 2" thick polyurethane foam insulation reduces heat loss
• High efficiency heating element
• Cold water inlet brings cold water to tank bottom to prevent mixing with heated water
• Anode rod equalizes aggressive water action for prolonged tank life
• Automatic temperature control
• Thermostat gauge to control temperature

A typical family of four in the U.S. uses about 80 gallons of hot water each day. To heat that water with electricity takes about 16 pounds of coal. In sunny Colorado, a standard solar hot water system can supply 60% - 95% of this energy, pollution free from the sun, while saving its owners about $250 per year.

If you are ready to invest in a Solar Hot Water System, and save a lot of money on your utility bills, Silicon Solar has everything you need. Our 40 and 80 gallon Solar Hot Water Storage Tanks, for example, are available in both stainless steel and painted stainless steel. For larger Solar Hot Water Applications, you will also find Large Solar Hot Water Storage Tanks which can handle up to 2,500 gallons of water.
